trouble getting colorbox working

I'm needing a little help please.
Recently i have been trying to get my understanding and skills in silverstripe improved so i set myself a project as the best way to learn is to do. the project is to create a module that is based on the dataobjects as pages - part 2 create a product catalouge from www.ssbits.com. essentally i have added extra functionality this includes adding some custom images to the product detail. i wanted the content editor to be able to add extra images to the product and the end user to be able to view the images in a similar fashion to the image gallery. in order to acheive this i was using the example from the Silverstripe 2.4 - modules extension, themes, and widgets book in particular the intro page and image gallery chapter 7.
anyway this has sofar been largley succesfull and the backend works, i can add images give them a title etc on the front end the images display everything works until i click an image and then it just shoots to a resized image no colorbox?.
so far i have discoverd that ...

1. the path i have defined in config.php does not seem to work so the colorbox js and css files do not load
2. if i place the full path in the requirements they load into the page but colorbox does not work.

so here i am .... stuck i am unsure if i have everything setup properly although everything works except the colorbox there are no errors i am using SS 2.4.5 and have tested the Gallery module from the book in the same site and it works so the base setup is ok it's something i have or havent done.

sorry to ramble on but i hope the background is useful. as for code i can post or provide a link to download the whole module, (while it is still in early stages it will install and function but i have alot more i want to add and lots to tidy and finish).
